To obtain integrated form of Clausius-Clapeyron equation, ln (P2/P1) = (ΔHV/R) (1/T1 - 1/T2) from the exact Clapeyron equation, it is assumed that the____________________?
Correct answer: D. All A , B. & C.
- A. Volume of the liquid phase is negligible compared to that of vapour phase
- B. Vapour phase behaves as an ideal gas
- C. Heat of vaporisation is independent of temperature
- D. All A , B. & C.
Explanation
The integrated Clausius-Clapeyron equation follows by neglecting the liquid volume, treating the vapour as ideal, and taking the heat of vaporisation as approximately constant over the temperature range. Therefore all three assumptions are used.
